I had to leave my gliders for 2 nights last year because my sons and I were ALL attending their older brother's wedding in Boston.
I purchased very fresh fruit & vegetables - ones that would not spoil quickly if stored at room temperature. Green beans, baby carrots, dried figs, grapes, fresh blueberries and cherry tomatoes. I left a bowl with the SunCoast Chicken & Brown Rice dry food and I also left the dehydrated chicken (sold in the dog department - freeze dried with no preservatives) They had way more than they could eat in 2 days and 3 water bottles on each cage.
I usually have my sons home when I travel and they feed the gliders but since we were all going, the dogs went to the kennel, the cats got lots of food and water and a clean litter box in their bathroom (their usual bedtime space) and the gliders got a smorgasbord of fresh fruits and vegetables that would not spoil at room temperature and everyone did just fine.
Not the best for the gliders, but when circumstances make it impossible to be there it was fine. Probably would not be good for more than the 2 nights we were gone though.
Truthfully, I was more worried about my spoiled 6 lb mutts at the kennel than I was the gliders. They are used to sleeping on a bed, as close to a human as they can get. They did fine too.
